Effects of organophosphorus fungicides on cutinase activity from Glomerella cingulata causing apple anthracnose and infection of apple were investigated. Diisoprophylfluorophosphate (DFP) inhibited the enzyme activity indicating that catalysis involves an active serine. In inhibition of the enzyme activity by organophosphorus fungicides, I50 (molar concentration of fungicide at which the enzyme activity is inhibited 50%) of Hinosan and Kitazin P were 26.3 $\mu$M and 427.7 $\mu$M, respectively. At concentration of 10-3 M DFP and organophosphorus fungicides, the infection of G. cingulata was inhibited to 5% in comparison with 15% infection at the unwounded healthy control, but increased to 30% when added with 1 mg/ml of cutinase. Mycelial growth was 36 mm in colony diameter on the medium added with 10-4M of hinosan in comparison with 90 mm of the untreated control, but was 90 mm on the medium added with 10-4M of kitazin P showing lower inhibition than hinosan. The spore germination was more than 60% at all the concentrations of both fungicides.

Gas Chromatograph Mass Spectrometry (GC/MS)를 이용하여 순천만유역내 유기인제 제 농약의 분포특성을 규명하기 위해 해수, 담수 및 기수 시료가 분석되었다. 우리 나 라에서 최초로 유기인제제 농약 Kitazin-P가 해양환경에서 검출되었으며 그 농도는 최 고2.2 mg/l를 기록하였다. 또한 순천만 유역내의 지역적인 변화와 시간적인 분포도 아 울러 연구되었다.
